Kelsey and Becca guide viewers through building a classroom compost bin using a 2-liter bottle and other materials. They explain the composting process, emphasizing the importance of oxygen to prevent methane production. The video highlights the differences between compost bins and landfills, and provides tips for maintaining a healthy compost. Only biodegradable materials like fruit and vegetable scraps should be composted. The video concludes with a recap and directs viewers to additional resources on composting and reducing food waste.
